To all whom t may concern.' l

Be it known that I, NELSON Brown., a citizen of the United States, residing at La Farge, in the county of Vernon and State of Wisconsin, have invented a new and useful Concrete Culvert; and I do hereby declare the following to be a full, clear, and exact description of the invention,` such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improved concrete culvert, and an object of the invention is to provide a device of this nature, involving improved features of construction. One of the features of construction is the provision of an annular flange at one end of the culvert, the plane of which extends at right angles to the culvert having reinforcement rings, and a flange at the other end of the culvert, the plane of which extends at an angle to the body of the culvert,there also being reinforcement rings embedded therein. The body of the culvert has embedded in its wall Wire meshwork and reinforcement rings. Any conventional form of mold may be utilized for forming this particular construction of culvert.

ln practical fields the details of construction may be subjected to alterations, falling within the scope of what is claimed.

The invention comprises further features and combination of parts, as hereinafter set forth, shown in the drawings and claimed.

In the drawings: Figure 1 is a view in perspective of the improved culvert. Fig. 2 is a sectional view, showing the culvert arranged, so that a stream may ow therethrough. Fig. 3 is a transverse sectional view on line 3-3 of Fig. 2. Fig. 4: is a fragmentary sectional view partially transversely through the body of the culvert and looking in the direction of the flange 3, thereby showing the construction of said angular flange 3.

`Referring to the drawings 1 designates the cylindrical hollow body of the culvert having an annular flange 2 at one end, the plane of which extends at right angles to the cy lindrical body, and an additional flange at the other end designated by the numeral 3,' and arranged at an obtuse angle to the body of the culvert.

Embedded in the Wall 0f the body of the culvert are longitudinal rods 4, the ends of wh1ch are turned at right angles at one end of the culvert forming the portions 5, thereby strengthening the flange 2. The other i end of each rod a is bent forming the portions 6, extending at an obtuse angle corresponding to the angle of the flange 3, thereby strengthening the same.` Also embedded in the wall of the body of the culvert are annular rods 7, and an area of meshwork 8. This meshwork also extends into the anges 2 and 3, and conforms to their dispositions. The flanges 2 and 3 also have embedded therein circular or annular rods 9 and 10. By this improved reinforcing'means the concrete walls of the culvert and the flanges are held together.

The'invention having been set forth, what is claimed as new and useful is:-

l. A. concrete culvert comprising a cylindrical hollow body having an annular disk flange at one end, the plane of which flange extends at right angles to the body, said body having at its other end a flange extending outwardly and forwardly of the end of the culvert and at an obtuse angle to the body, reinforcing means embedded in the wall of the body and said flanges, said reinforcing means comprising wires extending longitudinally of the wall of the body and being bent at their ends to conform to the contour of said flanges, annular rings embedded in the wall of the body and the flanges and being upon the outside of the longitudinal reinforcing wires, a meshwork embedded in the concrete of the wall and the body of the flanges upon the outside of the rings, said meshwork reinforcing means having its end portions bent to conform to the shape of said flanges and bent over the rings and the bent ends of the longitudinal wire reinforcing members.

2. A reinforcing structure for concrete culverts having a flange at each end comprising longitudinal wires embedded in the wall of the body of the culvert and having their ends embedded in and bent to conform to the shape of said flanges, annular wire rings surrounding the longitudinal wires, spaced apart from each other and embedded in the culvert and the flanges thereof, a cylindrical hollow meshwork surrounding the rings and having flanges conforming to the eoA shape of the flanges of the culvert, said In testimony whereof I have signed my meshwork being embedded in the culvert, name to this specification in the presence of the flanges of the meshwork being' bent over two subscribing Witnesses.
